Composite vessel construction for cosmetic products

ABSTRACT

A composite vessel construction ( 1 ), specifically designed for cosmetic products, characterized in that it comprises an inner body ( 2 ), adapted to form the vessel body, and an outer body ( 3 ), having a configuration different from that of the inner body ( 2 ), the inner ( 2 ) and outer ( 3 ) bodies being embedded into one another during the molding of the construction ( 1 ). The outer body ( 3 ) is applied to the inner body ( 2 ) by co-molding.

BACKGROUND OF THE INVENTION

The present invention relates to a composite vessel construction, specifically designed for cosmetic products.

As is known, in making vessels for cosmetic and the like products, it is necessary to provide the vessel both with good operating properties and good aesthetic characteristics.

Usually, the vessels for the above mentioned applications are made of polyethylene, which material provides the vessel with the required mechanical strength and chemical resistance characteristics, however, this material severely limits the possibilities of “stylizing” the vessel with respect to its finished outer aspect.

SUMMARY OF THE INVENTION

Accordingly, the aim of the present invention is to provide such a vessel construction which, while having very good operating features, is also provided with very good aesthetic characteristics.

Within the scope of the above mentioned aim, a main object of the invention is to provide such a composite vessel construction, which can be made in a large series, and at a very competitive cost, with respect to prior like vessels.

Yet another object of the present invention is to provide such a composite vessel construction the outer configuration of which can be easily changed.

Yet another object of the present invention is to provide such a vessel construction the aesthetic requirements of which are not bound to the merely functional requirements thereof, such as the mechanical strength and its compatibility with the products to be held therein.

According to one aspect of the present invention, the above mentioned aim and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by a composite vessel construction, specifically designed for cosmetic products, characterized in that said composite vessel construction comprises an inner body, adapted to form the vessel body, and an outer body, having a configuration different from that of the inner body, said inner body and said outer body being embedded into one another during the molding of the composite vessel construction.

DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to the number references of the above mentioned figures, the composite vessel construction, according to the present invention, which has been generally indicated by the reference number 1, comprises an inner body 2, embedded in an outer body comprising at least a main outer portion 3 and at least an outer cover portion 4.

More specifically, the inner body 2 comprises a main portion 5, for example of a substantially cylindrical configuration, as in the shown embodiment, and a cover 6, designed for closing the main portion so as to provide the vessel body proper.

Advantageously, the mentioned inner body can be made of a strong material, such as a polypropylene material.

The top outer edge of the main portion 5 comprises an outer annular ridge 7, which must not be necessarily continuous, as shown in the figures, adapted to engage with an inner annular ridge 8, formed on an inner surface of the cover 6, to provide a snap and tight type of closure of the cover.

The main portion 5 of the inner body 2 can have, as in the shown embodiment, a bottom element 9, raised with respect to the bottom edge of the main portion 5.

According to the present invention, to the inner body 2 is applied, for example by co-molding, the mentioned outer body.

The latter comprises a substantially cylindrical outer crowned portion 3, encompassing the side surface of the main portion 5, which is also of substantially cylindrical configuration, and an outer ortion 4, applied to the top surface of the cover 6.

The cover 6 of the inner body 2 is advantageously provided with holes 10 for allowing the outer body forming material to penetrate therethrough, said outer body thereby also forming an inner portion 11 of the cover 6.

The inner portion 11 of the outer body provides, therefore, an exposed to the view surface, as the vessel construction is in an open condition thereof, and, moreover, it can cooperate to provide the sealing coupling, as the vessel construction is closed, as is shown in FIG. 7, with the top edge portion of the main portion 5 of the inner body 2.

Advantageously, the outer body is made of a rubber-like material, having aesthetic characteristics better than those of polypropylene, and also adapted to provide a good touch feeling.

The cover is coupled to the vessel body through a hinge assembly, which can be made by molding in a single piece with the inner body 2, or in a single piece with the outer body.

FIG. 4 illustrates a hinge assembly 12 formed as a single piece with the inner body 2 and coupling the main portion 5 to the cover 6.

FIGS. 1 and 5 show, as a modified embodiment, a hinge assembly 13 formed as a single piece with the outer body and designed for connecting the substantially cylindrical outer crowned portion 3 with the inner portion 11 formed inside the cover 6.

In this connection it should be pointed out that the hinge assembly exploits the elasticity of the material and comprises suitable cut-outs or lightened portions to favor the vessel opening and closing movements, without excessively stress the vessel material, thereby providing a sufficient number of opening and closing cycles.

It has been found that the invention fully achieves the intended aim and objects.

In fact, the invention has provided a composite vessel construction which is very functional from a mere operating standpoint while being provided with very good aesthetic characteristics.

While the inner body can be made in a substantially conventional configuration, for example in a cylindrical configuration, the outer body can be so contoured as to present a particular aesthetic aspect.

That same inner body, in particular, can be used for making different vessel constructions, each characterized by a different outer body, having different configurations and colors.

In practicing the invention, the used materials, as well as the contingent size and shapes, can be any, depending on requirements and the status of the art.
